exposed the internal jib sheeting architecture, a system critical for maintaining aerodynamic flow in the absence of traditional spinnakers. This incident revealed how teams are pivoting away from the brute-force winch systems of the past toward sophisticated, automated control surfaces.
, the transition to self-tacking jibs represents a fundamental shift in game plans. While self-tacking is common in skiff racing, scaling it to a 75-foot foiling monohull introduces massive loading complexities. The strategic challenge lies in the lack of separation between the sheeting point and the sail's clue. Teams must now engineer ways to control sail twist and depth without the traditional wide sheeting angles of years past. The jib is no longer just a headsail; it is a precision-tuned foil used to guide airflow onto the main sail during downwind legs.
track system hidden beneath a voluminous foredeck recess. By moving the turning point, they can flatten the sail for upwind efficiency or deepen it for downwind power. Conversely,
has opted for a double-sheeting system. This setup uses two sheets anchored to different points on the clue board, allowing them to adjust the sheeting angle on a continuum without heavy internal machinery. It’s a masterclass in simplicity versus mechanical advantage.

designs suggest a move toward rigid, radius-based tracks that prioritize consistent tension. The lesson for every coach and player is clear: resilience is built into the design before the race begins. As teams refine these systems, the margin for error shrinks. The winner won't just be the fastest crew, but the one that masters the mechanical intersection of aerodynamics and structural integrity.
